PATENT' OFFICE a conrom'rov or NEW YORK SELF-INKING FOUNTAIN PEN original No. 1,880.128, dated septembe- 27, 1832, Serial No. 605.229, filed April 14, `1932. Application tor reisse filed October 13, 1932. Serial No. 637.663.

The invention is a fountain pen that manufactures its own ink as it is used from dye cartridges inserted in achamber in the feeder member below the nib, by water contained 'in the sack which feeds thru the dye carown ink in which the ink sack of a fountain pen is used as the water reservoir by which the ink is manufactured.

A further object of the invention is to provide a fountain pen having a liquid reservoir.

A still further object of the invention is to provide' a dye Cartridge for fountain ens that may be inserted in the feed and is a aptable to supply ink as water flows therethru.

And a still further object of the invention is to provide a fountain pen that manufactures its own ink which is of a comparative- With these ends in View the invention embodies a fountain pen having a chamber in the feed below the nib in which dye cartridges may be contained.

Other features and advantages of the invention will appear from the following description taken in connection with the drawin, wherein: D

igure 1 is a View showing a longtudnal section thru the pen. e

Figure 2 is a view showing a cross section thru the feed. v

Figure 3 is a view showing an end view of the feed. v

Fi re 4 is a view showing one of the dye cartrdges with part broken away.

Figure 5 is a cross section thru the pen taken on the line 5-5 in Figure 1.

In the drawing the pen is shown as it would be made wherein numeral -1- indicates the body of the pen, numeral 2 .the cap, and

. will correspond with the slot numeral 3 the dye Cartridge storage chamber as may be used in the pen. The pen 1 may be of any type or design,'may be arranged in any desired manner, and any make of pen may be used. In the designshown the casing, as indicated by numeral 1, is frictionally held to a base 4 to which a sack 5 is attached, as shown, and the lower end of the base is provided with an opening 6 into which a nib 7 and the feeder member 8 are inserted, as shown. It Will be understood that a nib of any type or design may be used and a'lso that the nib may be changed as often as may be vdesired. The feeder member 8 is made, as shown in Figure 2, with a cylindrical chamber 9 extending upward from the lower end to the'point 10 and then from the end of the chamber 9 to the upper end of the 'feeder is a very small passage ll connecting the chamber 9 to the water reservoir. In the upper part of the feed is a longitudinal slot 12 and I the lower end is connected with a small bar 13, as shown.

The dye Cartridge 14, which is inserted in the opening 9, is made, as shown in Figure 4, with a thin cylindrical casing having openings 15 in the upper side which, when the dye-Cartridge is inserted in the opening 9, 12, and at one end of the dye Cartridge is a projection 16 that may readily be caught bythe finger nail or other object, to withdraw the dye Cartridge from the chamber 9. The opposite end of the dye Cartridge is open and the interior is filled with an ink dye, as indicated by the numeral 17, and as the device is used water will flow downward from the sack 5 and wash the ink from the upper end of the dye cartridge thru the openings 15 and as the pen is used continuously the water will continue to flow downward into the dye Cartridge and all of the dye will be washed out. This action constitutes the manufacture of the ink so that the pen actually manufactures its,

lower end of the casing 1 when the pen is in a closed position, and may also be frietionally held in the upper end of the pen when the pen is in use.

= derstood that the storage chamber 3 may be i i feeding water to the dye cartrdges and still' formed in any other manner and may be located at any other point in the pen.

It will be understood that other changes may be made in the Construction without departing from the spirit of the invention.,

One of which changes may be in the use of the device in a pen of a different style, 'another may be in the use of other means for another may be in the use of a cap of a diferent design or type.

The construction will be readily understood from the foregoing description, In use the pen may be provided as shown and it is preferred to fill the water sack 5 by the clip 18 before the dye Cartridge is inserted, however, the pen may be dipped in water and the sack refilled at any time, as may be desired. It will be noted that ordinarily there will be' no action in the pen, however, as pressure is ap'plied to the nib 7 the working action thereof will cause a small amount of water to feed thru the dye cartridges and this will supply ink to the point. The dye cartridges may readily be w'ithdrawn and a new cartridge inserted from the chamber 3 as the ink is used. The device thereby provides a self nking fountain pen that manu-- actures its own ink as it is used.

- Having now particularly described andascertained the nature of my said inventon and in what manner the same is to be performed, I declare that what I claim is 1. 'An improved fountain pen comprising a barrel adapted tocontain water, a feeder member mounted in' said barrel and having a bore extending longitudinally therethrough' communicating at its inner end with the inte- 'ior of the barrel and at its outer end being exposed outwardly of the barrel, said feeder member having a slot in its side wall communicating with the bore and opening outwardly, a pen oint associated with said feeder member an extending aboutthe slotthereof, and a Cartridge removabl and friction'ally inserted inthe bore of sai feeder member, said Cartridge comprising an outer metallic case having an inner open end communicating with the water in the barrel and a closedouter end exposed through the outer open end of the burrel, said case having a perforated side wall communicating with the slot of the feeder member, an ink making material in` said cartrid and a hook upon the outer closed end o the cartridge case exposed for withdrawin the Cartridge axially out of the feeder mem r.

2. An improved fountain pen comprising a barrel adapted to contain water, a feeder member fitted to said barrel and having a longitudinally 'extending bore communicating at its inner end with the water space in the barrel and being freely open at its outer end, said feeder member having a slotted side wall 'communicating with the bore, a penpoint associated with the feeder member and fitted about said slotted side wall, and a Cartridge member insertable in and removable from the outer open end of the bore with an outer closed end and an inner open end'in communication -with the water space of the ban-el, 'said Cartridge adapted to contain ink making material and having a perforated side wall in communication with the slotted wall of the feeder member.

3. In a fountain pen, a' liquid-containing barrel, a feeder member, a pen nib, and a cartridge containing ink dye and consisting of a -tubular shell having side openings, said Cartridge so arranged that the liquid will flow into said side openings in said Cartridge as it passes to the nib. v

4. In a fountain pen, a water .reservoir having an external opening through a passage- Way, means 'for holding ink consisting of a' removable Cartridge located in said passageway, said cartridge closed at one end and open at the opposite end and having a plurality of small openings in the wall thereof and having a projection at the closed end by which it may be withdrawn, said cartridge and projection also externally sealing said passageway.

5.- An ink cartridge for a fountain pen comprising a metallic tubular casing open at one endand closed at the opposite end with a plurality of small openings in the wall article of manufacture an ink carv York, State of New York, this 11th day of October, 1932.
